A Ginzburg-Landau approximation theorem for quasilinear pattern-forming systems in uniformly local Sobolev spaces
Théo Belin, Guido Schneider
Abstract
We prove that the Ginzburg-Landau equation correctly predicts the dynamics of quasilinear or fully nonlinear pattern-forming systems close to the first instability. We present an approximation theory in uniform local Sobolev spaces which is applied to a quasilinear Swift-Hohenberg model, to a quasilinear version of Bénard's problem with velocity dependent viscosity, and to abstract quasilinear reaction-diffusion-advection systems.
